Explanation

The Great Wall's base thickness varies by section, but 9.1m (about 30 feet) is a documented measurement for certain fortified stretches. The wall was designed to be extremely wide at the base to provide stability and allow multiple soldiers to march side by side. Some sections reach up to 9.1m at the foundation.
